Bean fruit development in different irrigation regimes

Abstract

The fruit development of Phaseolus vulgaris L. cv. Goiano Precoce was followed at different time intervals by means of volume and dry weight changes. The relationship between these values and age of the fruits could be represented by a 1^st and 2nd-grade polynomial function. Fruits from plants under a twice-a-week irrigation regime showed better development and weight gain. The influence of water regime upon the development of bean fruits was evident under the three irrigation regimes studied: the volume of the fruits was always higher in plants without water stress than in plants subjected to water stress.
